Koh-i-Noor Diamond

The Koh-i-Noor diamond is a 105-carat gem first recorded in a 14th-century Hindu text. According to The Sunday Times of India, the text carries a dire warning.

"He who owns this diamond will own the world, but will also know all its misfortunes. Only God, or a woman, can wear it with impunity."

Victims of the alleged curse are said to have included the son of Mughal Emperor Babur, who was exiled from his kingdom; Shah Jahan, who was imprisoned by his son; and Nadir Shah, who was assassinated.

The gem became property of the British royal family in the 19th century and is on display at the Tower of London.
